Ubuntu :: How To Change Dynamic IP
Mar 27, 2010
Is there any way to change Dynamic IP on Linux ? as smeagol271006 mentioned in his thread , we have to disable avahi daemon to get this above code to work properly. dhcpcd trick worked like a charm for me but i have 2 major problem.
problem 1. I always get the same dynamic ip. I need to change dhcpcd -r IP by hand to get a new dyn IP.
problem 2. since i disabled avahi and network manager , i can no longer use DHCP feature . I have no choice but to enter dhcpcd code snippet manually to assign a dynamic IP for every system restart. Is there any clean way to get a new dynamic IP without using dhcpcd ?

Fedora 12 64bit What will be the correct steps changing dynamic IP to static IP on F12 console, instead of on Gnome running;
System -> Administration -> Network -> Edit, etc.

So when I upgraded to Slack64 13.1 on my asus MB homebrewed desktop and Slack 13.1 on my compaq presario a900 laptop, I started having issues with the xterm title (in Terminal--not Konsole) being too dynamic. By "too dynamic" I mean that I can't actually change the title. The dynamic title (from my .bashrc) is basically just pwd. Whenever I try to set the title (via terminal->set title (menu)), I changes it for a split second, and then reverts back to the dynamic title.
This is merely a petty annoyance, so to get around it, I added an xtitle function that I grabed somewhere online (just echos "�33]0;$*�07"). So for nano-ing some file, I'd type:xtitle some_file.txt; nano some_file.txt
That works just fine (kind of annoying to type though). running xtitle alone won't actually change the name either though (I'm pretty sure it's the same command as what terminal does anyway). That is, running: xtitle some_file.txt
changes the title for a split second, and the reverts back to my old pwd.What I really want is to have it dynamically name it "some_file.txt" whenever I use nano, but that appears to be a functionality of zsh (with the preexec() fxn).I'm wondering if anyone else has had this problem, and if you have a fix for it.

I want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.
So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.
Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.
Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.
Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.
I hope I explained my problem as well.
My configuration file:
# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file
In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.

I've got Apache installed so I can learn perl and php, and to show off, of course. I just realized last night that my IP isn't what it was three months ago.does anyone here have any experience with a dynamic IP program (like DynIP back in the day.) .. I've seen a few options, but I was hoping someone would have some experience.

I have a Dell Inspiron N5010 laptop that came with Windows 7 installed and a dynamic disk. I want to install Ubuntu but I have the following constraints:
I don't want to lose any data. I don't want to lose my current Windows installation. If I tried to make a system image it will be very large (about 40GB)
What are the available options?

i would like to know if there is anything like this out there or in development and if not i think there should be. i feel that one of the areas that ubuntu still lacks majorly is when it comes to handling multi display.most people these days are using notebooks and are moving around a lot, and if your like me working as a software dev you need to be able to work from home running a different external display next to your internal, then when you get to work you need to maybe run two external displays or maybe a totally different display next to your internal, sometimes you'll need to connect to a projector in a meeting and do a demo.
At the moment, there is no easy way to do this unless you have a half an hour everytime to configure your displays manually,which goes without saying that its not quite what anybody is looking for.i'm looking for something that works similar to OSX's display manager.where you plug in a screen and poof, its there. and then mayb you can configure what your system should do when that specific monitor is plugged in and it will remember that configuration. so for instance you have a internal 15" with a res of 1440x960 then you want to plug in your 1080p 24", so boom it picks it up but its not configured yet.so it jus mirrors by default, then you decide ok, when this screen is pluggd in, i want it to extend my desktop onto it, and make it the primary monitor. ok cool so its set,so now when you plug it out, your system detects that your display setup has changed, then does a recheck of your active displays, and sets up the appropriate configuration, in this case only the internal is available so it will just go back to the internal, setting it back as the primary and moving all the windows that was on the external back to the internal.i think this would be a invaluable feature for a mobile professional.

I've read some guides on how to setup ssh with dynamic DNS, but can't seem to get it to work. My Linksys router is currently set to forward port 22, so I don't know why SSH still gives:
ssh admin@xxx.hopto.org ssh: connect to host xxx.hopto.org port 22: Connection refused In particular, I also have openssh-server running on the target machine. Given that I have port forwarding enabled, why would this be happening? If I try to login directly to the IP, I get the same refusal.

I need to obtain daily dynamic IP address from my router for remote user. In order to get into the router page, I need to login to it with ID and password.
Can I tell the server to do this every time it started up to login to router and extract the ip address and send out via email?
The router can only access through web interface and below is what I copied from browser.

I'm folding and I need it to only run on 6 cores instead of 8, and I have it set to do that but Ubuntu decides to bounce the load around the 2 extra cores as well, hurting my performance. Is there a way to disable it or set it to work only on 6 specific cores?

I am having a bit of a problem connecting to a dynamic WEP WiFi network.
Code:
Apr 15 11:39:31 MyComputer NetworkManager[943]: <info> Activation (wlan0/wireless): access point 'MyUniversityWifiSSID' has security, but secrets are required.
Apr 15 11:39:31 MyComputer wpa_supplicant[1002]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
[Code]....
I have googeled that specific error about the WEP line, and it *was* a bug at one time, but according to the bug tracker, it has been fixed. Not so, me thinks.
So, does the specific error above look familiar and does anybody know of a way to fix it?

My university uses 802.1x Dynamic WEP, with PEAP, MSCHAPv2, and no CA certificate. Our IT department actually provides instructions for Ubuntu, and they work, but I can't get it to work in Kubuntu. Here's the instructions using the Gnome Network Manager applet:
- Change the LEAP setting to Dynamic WEP (802.1x).
- Change the Authentication setting from TLS to Protected EAP (PEAP).
- Leave the Anonymous Identity option blank.
- Leave the CA certificate setting to None.
- Change the PEAP version to version 0 if running 8.10, or Automatic if running 9.04+.
- Leave the inner authentication setting to MSCHAPv2.
- Enter your username.
- Enter your password.
- Select OK. A warning message will appear about having no certificate; click Ignore.
- Click Connect.
I'm using Kubuntu 10.10. All the same settings are there for the KDE plasma network manager applet, but the connection always fails immediately. How do I go about debugging this? Is there a way to test this out from the command line? (WiFi in general works fine, on regular WEP and WPA secured networks; just having trouble with this one).

I am looking for a way to be able to access my PC from a remote place. The problem is that I have a dynamic IP. I have registered at dyndns and have found settings in the router to 'Activate Dynamic DNS' and then you supply your dyndns address, password and tell it to update the WAN ip address automatically. This works, however only internally and only to the router as opposed to my PC I am not interestes in accessing the router to configure that remotely, only accessing my own PC.
Is this something I can accomplish with:
A ZyXEL P-660R-D1 router
A dynamic WAN IP address
A PC connected to the router
A static IP address for my PC

I would like to setup GRUB on a USB where it automatically detects the available OS installations on the machine that it is plugged into.This could be useful if you messed up your default GRUB menu on a computer and would like to boot into the machine w/out booting Live-OS. Or if you have multiple Live-OS installations on a USB-Drive and would like to add/remove different installations w/out needing to update grub manually.
I know that Grub2 has a OS-prober feature that looks for other installations on the hard-drive, but will that work in either of the scenarios listed above?

trying to use this program [URL].. to work with my dynamic ip address so i can host a small website on my ubuntu 11.04 machine with [URL].. following is the install instructions and after that is the results of the first two commands: './configure' and then 'make' which results in the error at the bottom. im not sure what this means or how to fix it. any suggestions? the products website has no info.
The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type sh ./configure' instead to prevent `csh' from trying to execute `configure' itself.

We have Verizon as our ISP with a dynamic IP address. We published our website but the IP changes frequently. How can we set Network address translator(NAT) so our website can be published regardless of IP changes? We don't have domain name and have no intention for one.

From a friend I received a cdrom with Ubuntu 8.10 and recently I tried to install it on my laptop. The installation failed and moreover the volumetypes of the partitions, including the system partition, on my disc have been changed from "basic" to "dynamic" which is very annoying because now I cannot restore my backup. I have now spend a couple of days trying to restore my disc back to its original state but to no avail. Can anyone tell me how to change the volumetype of the systempartition (which cannot be deleted !!!) from "dynamic" back to "basic". My PC is a Dell Vostro 1720 with Windows 7.

Is it possible to add the routes to my routing table for dynamic pppoe connections? I have this setup on windows 7 with power-shell scripting and some 3rd party commercial pppoe client called Cfos, but since I'm now trying to move away from windows to Ubuntu and cant use the same programs anymore and its getting abit tricky now. I'm not trying to do any fancy load balancing here just some basic stuff which should be possible. Here is same basic info.
My ISP resets my pppoe connection every 24 hours. However the advantage of this is that I can call out 2 or more simultaneous PPPOE connections through the same modem. This is my routing table I wrote which has 5 PPPOE connections [URl]..Id like this to be automated when the PPPoes reconnect and the computer restarts.
